Figure 2-3 Energy production impact of blade length

Figure 2-4 illustrates that while longer blades add cost, the cost per meter can be significantly higher for longer blades and still present a net benefit to the LCOE. This dynamic encourages investment in research and developing in blade technology to improve efficiency, reduce loading, and optimize performance.
